Utilizing ultrasound, RFsignals, and superspeed, three companies are trying to change the way we charge our devices.
#1 uBeam Wireless has created a way to charge devices wirelessly through ultrasound. The prototype uses ultrasound to send electricity to devices up to 15 feet away. All it takes is a receiver on your phone, and your device receives electricity like WiFi. The device isn’t out yet, but you can learn more about it from TechCrunch and The New York Times.
#2 Nikola Labs turns RF signals (like Wi-Fi, Bluetooth, and LTE) into power for your device. The company has created an iPhone case that can wirelessly charge your phone wherever you go. According to TechCrunch, the case converts wasted energy from the phone and converts it to battery life, powering it up to 30% longer. Nikola Labs will launch a Kickstarter campaign with the case soon.
#3 Nucleus Scientific wants to charge a phone in the amount of time it takes to fill your car’s gas tank. Their new Intelligent Energy System “reduces battery charging times from hours to minutes while extending lifetimes considerably,” according to the company’s website. The technology is still patent-pending.
